The main frame B of the machine preferably comprises a pair of suitablyspaced standards I- .upstanding from a base-plate 2 supported preferablyby and between the front and rear walls 3 and 4, respectively, of theshell or housing A. Intermediately disposed horizontally in the mainframe B and preferably extending forwardly from the rear thereof,-is apair of laterally spaced parallel guide-bars or 'rails- 5 preferablyintegral with the respective standards I, therails 5 at their forwardend projecting in bracketlike manner through a substantially rectangularaperture or slot 6 providedsuitably for the purpose in the front wall 3of the shell A. V

Accessibly for customers convenience supported exteriorly the housing Aon the bracketextensions of the rails 5, is a coin-depository whichincludes a shelf or table I having depending front and side flanges 8and 9, respectively, for concealing the exposed-portions of the rails 5and the space horizontally -therebetween, the shelf 1 at its rear marginl0 projecting'edgewise into the aperture 6, as bestseenin Figure 3.

For coin depositing purposes, I prefer to provide a coin-chute whichincludes a circular coinreceptive recess disposed centrally in said rearmarginal portion IU of the shelf |,"the front wall of the recess beingsuitably chamfered or provided with a sloping coin-channel or passageway|2, as best seen in Figures 2a and 16, for slidable insertion of a coinfrom-the top surface of the shelf 1 into the recess A plate l3 coversthe recess II and has its forward endportion |4- suitably bent or curveddownwardly for snugly fitting into-the coin-channel |2,"theplate-portion 4 having a transverse coinreceiving notch orslot l5suitably formed for determining or limiting the maximum dimensions ofthe particular-coin admissible for coin-depositing purposes into themachine. The plateportion I4 is further, for coin-manipulative convenience, provided with an arcuate finger-notch l6, as also best seen'inFigure 16. V

The :coin-feedingmechanism of the machine includes a, slide orshiftable'frame-C, best seen in Figure 14, said frame C supporting ashiftable coin-engaging member or plate normally disposed in forwardlypresented or retracted position beneath the coin-shelf 1, saidplat'e I!having in itsrearward marginal portion a semicircular notch |8 adaptednormally for registration with the recess H in the shelf 1. The plateIT, for rearwardly shiftablecoin-feedingactuation thereofprojectinglyfrom the shelf '1, is

preferably integrally connected to a pair of spaced rearwardly extendedside bars l9, each depending from a side of the plate for reciprocationin pair of opposing horizontally disposed ways 20 providedlongitudinally in the rails 5 of the frame B complementary to theside-bars 19, Figure 2. i I Supportedbeneath the plate I! between theside-bars I9, is a block 2| havinga pair-of spaced parallel longitudinalhorizontal bores 12 2 peripherally adjacent the underside of the plateI"! for guiding reception of the respective forward ends of acorresponding pair of coin-carrying plungers 23, which at theirrearwardly projecting ends are suitably reduced in section, as at 24,for abuttingly engaging a connecting transverse bar preferably, forslidable discharge of a coin there- ,over, flush with the tops of theplungers 23. The

plungers 23 are actuable shiftingly in the bores 22 normally forextension from the block 2| in coin-carrying position under and acrossthe recess H and notch |8 for deposit of a coin therefromsupportinglyupon the plungers 23. The plungers 23 for coin-feeding discharge of thecoin therefrom are adapted for retraction into the block 2| until thebar 25 passes beneath the plate H, the block 2| having a suitable recess2 la for reception of the bar 25 in said retracted position, and saidcoin, I might add, being engaged by the walls of the notch IS on suchretraction of the plungers 23 under the plate I! for discharge of thecoin over the ends of the plungers, as shortly appearing.

The plungers 23 are preferably constructed of electrically conductingmaterial, and the block 2| and connecting bar 25 are, for electricallyinsulating the plungers 23, constructed preferably of suitableinsulating material.

Engaged between the shoulders of the reduced plunger-ends 24 and the bar25 and depending from the bar 25, is apair of preferably flexiblecontact members 26 for cooperative engagement, when the plungers 23 aredisposed in normal or forwardly shifted position, with respectiveterminals'26a, 2611, connected in the electrical circuit of the machine,as later appearing, said plungers being normally insulated from eachother for coin-conducting connection thereof on deposit of a cointhereon.

At each of the laterally opposite ends of the bar 25, is an outstandingear or lug 21, each carrying a rearwardly projecting horizontal rod 28adapted for sliding movement in and through a fixed transverse plate orframe member 28 connectingv posts I04 upstanding from a crossmember I03mounted on the frame members Each of said rods 28 is provided at itsfree or rear end with a depending hook or stop 29 adapted for impingingthe rear side of the plate 28' for automatic shiftable extension of theplungers 23 from the block 2| on retraction thereof, as will later moreparticularly appear.

Also preferably at least one of the plungers 23 is provided with anaxial forwardly projecting rod 30 disposed in the corresponding one ofthe bores 22, said rod 30 having preferably a depending hook 3| adaptedfor engagement with the front side of the block 2| for limiting therearward movement of said plungers in said block 2|.

Projecting laterally outwardly from the opposite sides of the frame C atan intermediate point from the respective bars I9, is a pair of opposedpins 32, each having a suitably reduced end 33 passing through thecorresponding bar l9, said reduced-end 33, for securing the pin 32 tothe bar I9, being preferably threadedly engaged by a nut 34 abutting theinner side of the bar l9, and it may be stated that preferably securedbetween each of the nuts 34 and the corresponding bar 9, is a stop-angle34', the inturned leg thereof being forwardly presented, as .best seenin Figures 8 and 14, for a purpose later appearing.

V The pins '32 extend through and reciprocate freely in slots providedlongitudinally in the respective rails 5 of the frame B..said pins 32projecting sufliciently beyond the side members I of the frame B foroperative engagement each between an endwise presented'rearward 1ug36:and a like endwise presented forwardspring 31pmvided on the swingable,end of thecorresponding one of a pair of vibratory levers 38, saidspring 31 being attached by a suitable fastening element 39 to the shankof the lever 38,'as best seen in Figure 3.

The vibratory levers 38 are disposedione on each.

side of the frame B for operation thereof in unison, said levers beingfixed on atransverse shaft 40 rockable in suitable bearings 4| depend-ving from the opposite sides of 'thewbase plate, 2.

At an intermediate point, the shank of each lever 38 is suitably widenedand apertured for providing an irregularly shaped ring-cam,42, which,for'oscillatoryactuation of the lever 38 for correspondinglyreciprocatorily shifting the slide C, is adapted, for cooperation with awrist pin 43 mounted on a rotatory face-plate or disc 44, the pin 43being annularly actuatedon rotation of the disc 44 for cperativelyengaging the, several interior earn-walls of the cam,ring, 4,2 withcorresponding vibratory. actuationhof' the lever associated therewith,as will presently more particularly appean'but I may at this timebriefly describe the several cam-portions of, the

ring-cam 42, as follows, reference being had to Figure 3: a designatesthe-cam corresponding to the normal or non-operative coin-depositing-position of the lever 38, the slide C being in extreme forwardposition; b designates a rising cam for actuating the lever 88 and slide0 to extreme rear coin-feeding position; 0 designates afalling por tionfor allowing the lever 38 to beactuated forwardly by means of theresilient member 41a operating through shaft 40 to said lever 38' andthus returning the slide C 'to coin-weighing position, and d is a dwellor concentric portion of the cam for holding the slide C in saidcoin-weigh ing position for a period. of time pending the completion ofthe coin-gauging and selecting operations of the machine; e designates arising portion for shifting the slide C to extreme'forward position fordischarging the coin from the gaug ing mechanism; and f designatesw adwell or concentric portion designed to permit the comple ticn of thecoin-distributing operation before the machine comes to rest. Thiscompletes the operativecycle of the'machine, the several opera ticnsmentioned being presently more particularly described. V v

The discs 44 are respectively fixed on the op posite ends of atransverse rotary main-shaft 45 journaled in suitably provided parts ormembers of the frame B, the'shaft 45 being rotarily actuated by means ofa gear 46 mounted thereon and meshing with a worm 41 mounted on a shaft48 best seen in Figure 3 frame-52; best seen in Figure 15, divested ofits movablyattached parts, tSaid frame .52 for'coimreceptive feedingpurposes is disposed normally" in alignment with the plungers 23 betweenthe side bars l9, the front end of the frame 52 be-.- ing swingablydisposed rearwardlyadjacentthe' plate 28 Suitablyfor coin-weighingpurposes,v the frame 52 is provided with intermediately dis-.

A pair of ears or lugs 64 project laterally, from respective sides ofthe forward end of the -plate 59, and are adapted-for impingement-by themembers 34 of the slideC for forward shifting coin-discharging actuationof the plate 59, as will later appear. Presented forwardly from each car64, is a pair of spaced oppositely flaring upper and lower fingers 65,each pair of said fingers 65 forming a throat, as at 66, adapted forguiding reception of the advancing opposite side edges of the plate I1on coin-feeding rearward actuation thereof for cooperativehorizontalalignment of the opposing walls ofthe notches, I8, 69, Figures5 and.l6.

Intermediately'upstanding from opposite sides of the frame 52, is a pairof standards 51, the plate 59 being suitably narrower for passingbetween said standards 61 and having opposite lateral shoulders 68,which for precise positioning of a coin a predetermined distance fromthe pivotal axis of the balance-frame 52, are adapted for impingementwith said standards 61 for limiting the rearward movement of thepositioning plate 59,

Figure 8. I

-Mounted on the balance frame 52 for yielding thickness-gaugingvgripping cooperation with a coin, disposed upon the upper surface of theforward end .of the frame 52 by said rearward actuation of the plate 59,is a so-called minimumthickness gauge E, which includes a coin-engagingshoe 69 projecting forwardly from anoscillatory lever Ill extendinglongitudinally of the frame 52, said lever III, for coin-responsiveoscillation thereof, being intermediately pivotally supported on a'lower transverse shaft H mounted through the standards, 61. The lever I9is normally urged in coin-gauging position bymeans of a resilient memberor leaf -spring 19a suitably for the purpose attached at one end to theunderside of the lever 10: near: the pivotal, point thereof for yieldingdownward engagement of the other or rearward end of the spring 10a withthe frame 52.

Adjustablythreaded insulatably through the rearward preferably narrowedswingable end of said lever 10, is a depending contact screw, 12normally spaced from, but adapted, on coin-gauging rocking actuation ofsaid lever 10, for cooperative engagement with the upper or yielding armof a horizontally disposed U-shaped resilient spring-contact .13, thelower arm thereof being insulatably mounted on a fastening element orbolt 13 of conducting material insulatably passed through a boss 13aprojecting rearwardly from the rear-end-cross member 131) of the frame52. Said contacts 12, 13, are normally disengaged, but. are adapted forcircuit-closing engagement thereof on gauging cooperation of the leverHi with a coin above, the minimum thicknessegauging lever 10,

being for such purpose intermediately pivotally supported on an'uppertransverse shaft 16 mounted through the standards 61, whereby. thelevers 15 are adapted for oscillation independently of the lever 19andof each other. A pair of resilient members or leaf springs 11 ismounted on the upper, side of.the.;lever,10;.for yielding .upwardengagement of the rearward ends of said springs TI. each with one of thelevers 15.

Each of said levers 15 carries, at its hence up- Wardlyurged'rearwardend, a contact 18 adapted normally for impinging circuit-closingengagement with the corresponding one of a pair of contact-screws orposts 19 dependingly threaded adjustably through the upper transversebar of an inverted U-shaped frame 80 upstanding from the rear member 13bof the balance frame, 52.

The contacts 18, l9,of either, or both, of the levers 15 are normallyengaged, but are adapted for circuit-opening disengagement thereof ongauging cooperation of the particular lever 15 with a coin of greaterthan maximum thickness.

It may at this timebe stated that the gauging levers 15 are adapted forengagement of their carried fingers 14 with the depressions, or thevalleys, as may be said, of the coin being measured. In this particular,it is to be borne in mind that most, if not all, coins are embossed,more or less, at their central portions; hence, as best seen in Figure22, the functionof the gauge-fingers l4 is'to each independently explorethe lateral side or marginal portions of the coin for locating andaccurately determining the lowest point of said valleys or depressionsof one face of the coin as related to the plane surface of the frame 52engaged by theother face of. the coin. As the embossed portion of thecoin is apt to be irregularly shaped, the pair of fingers 14 areindependently actuable in order that at least one may be engaging avalley even when the other is engaging a height of the embossment.

On the other hand, the gauging lever 10 meas- L ures with its carriedshoe 69' the height or total thickness of the central or embossedportion of the coin, it being understood that, in each case, the coinmust be of a certain predetermined standard of thickness at the valleysand the height to pass the tests imposed upon it by the respectivethickness gauges E and F.

Additionally, however, the machine is adapted for subjecting the cointoan accurate test of its weight, coincidental with the thickness test.For such coin-weighing purposes, the balance D may be adjustablycounter-balanced, for predetermined weight of the coin being gauged, bymeans ofa weight 81 slidably mounted on a pair of spaced parallelWeight-supporting rods 82 longitudinally projecting under the frame 52from an inverted U-shaped hanger 83 depending suitably from the endmember 13b. 'Said weight 8| is longitudinally shiftably actuable forbalancing purposes by means of a screw 84 threadedly engaging the weight8| and journaled suitably in the depending cross member of the hanger83, said screw 84 forconvenient manipulation thereof being provided witha knurled head 85.

A so-called'balance-switch-arm 86, preferably of conducting, material,depends from an insulation block' 81 mounted for the purpose suitably onone of the shafts 53 and secured thereto by suitable fastening elementsfor oscillation with the frame 52. The lower end of the arm 86 ispreferably right-angularly bent providing a projecting contact 86adapted for swingable actuation on oscillation. of the balance D.Adapted for movement at selected intervals for intersecting the arcuatepath of the contact 86', is a balance switch-contact-screw or post 88adjustably threaded dependingly through one or the swingable end of anoscillatory balance-switch lever 89, whose other or hinged end isdisposed forwardlylof the main shaft-45 and pivotally supported on ashaft 90 mounted through bearings 9| upstanding suitably from the baseplate 2 of the frame B, saidlever 89 being normallyheld yieldingly inelevated open-circuit position by means of a resilient member orleaf-spring 92 attached to one end of the underside of the lever 89 fordownwardly bearing its'other end on the base plate 12,

Fixed on the shaft 45, is a plate-cam 93 having aniedge-cam tooth 93aadapted for engagement, at a selected period of operation of themachine, with the lever 89 for downward actuation. of the contact-screw88 in circuit-closing direction, said contact 88 being adaptedforimpinging cooperative engagement with the contact 86 on coinweightgauging actuation of the balance D rely projecting from, and secured bynuts-99 in electrical connection with, the contacts I9, leads suitablyto the other side of the electrical circuit of the machine, as willpresently more particularly appear.

i The coin distributing mechanism (3' of the machine includes apreferably cylindrical open ended vertical coin-chute I disposedgincoinreceptive position in front of'and beneath the forward end of thebalance D for gravity discharge of coins therefrom into said chute I00on forward actuation of the plate 59 following the thickness and weightgauging operations of the machine. Preferably the chute I00 is clampedby a semi-circular band I0] to a complementary saddle I02 formed in thecross-member I03 transversely disposed between and supported by theframe members I. As-has been stated, for supporting the plate 28', thepair of posts I04, upstanding from the cross-member I03, is-provided.Preferably, the lower open end of the chute I00 terminates just abovethe front margin of the base-plate 2, thelatter having at this point asuitable aperture I05closed byca front wall I06 formed with a forwardlysloping upper edge I01, as :best seen in Figure'5. The

Wall I00 depends belowthe base2- for supporting a forwardly'projectingbracket-like-coin-receiving or reject-tray I08,;accessib1y for customersconvenience presented through the front wall 3 of the housing A, asshown in Figure 3.

Normally closing the lower end of the chute I00, is an oscillatory valveI09 suitably mounted on a rod or shaft I I0 journaled through a pair oflugs I'II depending'suitably for the purpose from the opposite sides ofthe chute I00.

V For tilting actuation of the valve I09 in alternate coin-distributing,directions, said rod H0 substantially G-shaped cam-follower us,thelatfor, it will beseemhaving; a universalmovement,

respectively. Said follower I'lIl.;includes apair of cam-embracing jaws,ofwhichthe upper jaw II9 preferably rearwardly-projectsa greaterdistance than the lower jaw I thereof, said jaws I I9, I20,being-disposed'o'n opposite sides of the mainshaft 45 and-carryingattheir respective ends opposed cam-engaging teeth t2I,- the'diametricalaxis of'said; teeth preferably for most efiicientoperationof the device being substantially at right angles to theaxis-connectingthe pivot pinII5 andjshaft 45.:

The follower i I &is adaptedifor coin-responsive selective engagementwith a pair of-axiallyaligned positive motion edge cams I22, I23,,onecam, as ;I22, being adapted for I actuating, said lever-I I4 inmne; orcoin-rejecting, direction and theother cames, I23, being adapted'foractu that is, adapted,for both .vertical and horizontal ating-said'leverin opposite, or coinaccepting,

In actual practice, Iprefer to mount a drum-I24 on the shaft45, said drum having a diameterto revolve-between the teeth I2I, one endof the drum carrying the cam I22 and the otherend the cam I23, a shortcylindrical, or neutral section of the drum I24 being providedintermediate said cams, as best seen in-Figure 18.

For brevityfl shall referto theouter cam I22 as the reject cam, andthe;inner cam I23 as the acceptlcam. The cam I22 is, preferably, formedwith a radially depressed cam-notch I25 and a complementarydiametrically opposite radially projectingrcam-tooth" I25; in" a similarmanner, the cam I23 isformed of a radially proiecting cam tooth I26disposed, however, axially opposite the notch I25, there beingfhence,die-"- me'trically opposite the" tooth I2 6 a complementarycam-notchl26' axially opposite the tooth I25.

l The distributing mechanism G is co "trolled by afInagnetic-selecto'rH, which includes amagnet I29, mounted suitably in the frame B above themain shaft 45 and havingapole I29 a'dapted for magnetic cooperation withan armature I30 upstanding from thefupper jaw II9 of the'follower 'II8.Normally; as Bestseen'in Figure 19,.. the armature I30 isQsp aced fromthe pole I29, the fol- 'lower lIfl beingireelyswingablefor engaging thecam I22, but on energization of "said magnet I28, the followertl I8 ishence inwardly shifted'onto the accept cam I23,- shown by dot-dash linesin Figures 18, 19,;whereby said cam I23 acts to elevate thefollower II8-, ;swinging the lever" II4 rearwardly, and tilting the valve I09 fordischarging,,:through the-aperture I05, and-into asuitable hopperdisposed in the bottom of" the casing A, any coin contained at that timein the chute I00, such coin, it will be understood, having been acceptedby the gauging mechanism asof correct weight and dimensions. Thearmature I30 carries a rearwardly and inwardly projectingswitch-actuating lifter-arm I3I of insulating material, 'adapted, onfollowershifting energization of the magnet I28, to be positionedbeneath, for subsequent lifting impingement with, a resilient springswitch contact arm I32 of conducting material. The contact arm I32, Imay here state, constitutes the movable memberof'a double-throwso-called selector switch I33 mounted suitably on an insulatin'gblockI34 disposed in the rear portion of the'frame B, said switch I33comprising an upper pole I33a and a lower pole I33b, and said switch I33 being suitably, as will later appear, connected in the electricalcircuit of the machine, with the contact arm I32 normally engaging thelower pole I33b. However, on follower-lifting actuation of theaccept-cam I23, the lifter arm I3I acts to lift the contact arm I32disengagingly from the lower pole I32b into circuit closing engagementwith the upper pole I32a," as best seen in Figure 17 For energizing theseveral electrical circuits of the machine, as presently appearing, abank of cam-operated switches is provided, best seen in Figure 20, andnow to be described. Mounted on the shaft 45 preferably adjacent thegear 46, is a plate-cam I35, which is concentric with the shaft exceptfor a single peripheral notch I 35a, and which is adapted forcooperation with a single polespring switch I 36 forwardly projectingfrom theinsulation block I34, as best seen in Figure 20, said switchconstituting the cut-off switch adapted for controlling the supply ofelectrical energy to the machine. The lower or movable contact member ofthe switch I36 carries an insulation follower I36a normally residing inthe notch I35a in circuit-opening position, but adapted, on rotation ofsaid cam I35, to at once liftingly engage the periphery thereof incircuitclosing actuation of the switch I36 duringythe cycle ofoperationof the machine, that is, for one complete revolution of theshaft 45, on completion of which the supply-circuit is interrupted andthe machine brought to'rest'.

I Axially adjacent to .the cam I35, is plate cam I31 adaptedforcooperation'with ,a single pole spring switch I38 also forwardlyprojecting from the insulation-block I34, theswitch I38 being adaptedfor controlling the supply of current to the movablemember I32 of' theselector switch I33. The lower or movable contact member of-the switchI38 carried a follower I38a adapted normally to engage the cam I31 incircuit opening'position of said switch. Rotation of the cam I31,however, causes the'follower I38a to reside on the circuit-closing dwellI31aofthe cam, substantiallyduring. the period of time that the selectorswitch .I33 is subject to actuation by the lifter-arm I3I of thedistributorEJ Next adjacent to the cam I31, is another cam I 39 adaptedfor cooperation with a single pole spring switch "I40 likewise forwardlyprojecting from the insulation-block 7 I34, the switch I40 beingadaptedfor controlling the supply of current from the switch I33 .to thevending machine proper (not shown) The lower or movable contact memberof the switch I40 carries a follower I400: adaptednormally to engage thecam-I33 in circuit opening position of said switch. Rotation another ofthe cam I39, however, causes the follower I40a to be engaged inswitch-closing actuation thereof by a-tooth I33a of the cam I39, suchengagement occurring just before the switch I38 is opened by the camI31.

Preferably, the upper part of the casing A is provided with acompartment I 4| having in its front wall an opening I42 glazed with agreen glass or the like, the'compartment I4I having therein a lamp I43,referred to as the accept signal, adapted for illuminating thecompartment I4I for visually indicating the acceptance of a coindeposited in the machine.

Below the compartment I 4|, is another compartment I44 having in itsfront wall an aperture I45 glazed with a red glass or the like, saidcompartment I44'likewise having therein a lamp I46, referred to as thereject signal, adapted for illuminating the compartment I 44 forvisually indicating the rejection of a coin deposited in the machine.

Figure 9 diagramatically illustrates the electrical circuit 'of themachine and also the relative arrangement contours of the several camsmounted on the shaft 45, the View, in such regard, being considered astaken from the rear or the machine and the apparatus in normal positionfor deposit of a'coin in the machine. "Electrical energy from a suitablesource (not shown) is supplied to the machine through a pair of leadsI41, I41, the supply lead I41 having two branches,'one going to thestationary or upper pole of the switch I36, and the other to the contact20a.

' From the lower or movable pole of the cut-off switch I36 extends alead I48 connecting with a lead I49 extending from the contact 26a tothe motor 5I. From the lead I48 extends a lead I50 connecting with themovable pole of the switch I 38 and also through the pigtail 94 with thecontact 88 of the balance switch lever89.

. From the stationary-pole of the switch I38 extends a lead I5Iconnecting with the movable pole I 32 of the selector switch I33.

From the lower stationary pole I 33b of the selector switch I33 extendsa lead I52 connecting with one side of the reject-lamp I46, the other'side thereof being connected by a lead I53 to a lead I54 extending fromthe motor 5| to the return line wire I41.

From the upper stationary pole I33a of the switch I 33 extends a leadI55 connected to one side of the accept-lamp l43, the other side there-'of being connected also to the lead I53. The lead I 55 from the switchI33 has a branch I56 connected to the stationary pole of the switch I40,the movable pole thereof being suitably connected by a lead I51 with thevending machine for supply of operative current thereto, a return leadI58, as shown in Figure 9, extending from the vending machine forconnection with the lead I54.

Suitably connecting with the'pigtail 91 of the gauging mechanism, is alead I59 extending to oneside of the magnet I28, the other side thereofbeing connected through a lead I60 with the return wire I41. 7

' In use and operation, the cooperant parts and their severalparticularelectrical circuits are normally, that is, when the machine is at rest,in coin depositing position and disposed as best seen in Figures 2,.3,5, 8, and diagrammatic Figure 9.

Referring now to Figure 9, deposit ofa coin in the machine, indicated bythe dotted circle I6I establishes metallic connection between theplungers 23'; which are, at this time, disposed for engagement of theircarried contacts 25 respectively with the contactsiiia, 26b, hencecurrent flow is established through the lead I41, plungers 23, coin II,and lead M9 to thehiotor' 5I, thus starting the machinein" motion.

On initial movement" of the shaft 45,- the cam I35 closes the switchI36, sustaining the supply of current to the circuits I41, I48, I49,after the plungers 23 have become disconnected from the motor-circuit1,149; occurring on'rearward coin-feeding actuation of the slide Cresponsive to engagement of the wrist pin' 43 with the portion b'of thering-earn".

Thecoin-carryingplungers 23 move rearwardly with the slide C,untilthe'bar 25 impinges the plate 28, whereupon, as the plate- I1"advances,

, the plurig-crs 23 are retracted'thereunder, the coin being meanwhileengaged between the opposing walls of the respective notches i8, 60-.Further rear-ward movement ofitheplate" I1 causes corresponding rearwardactuation" of the positioning plate 59 over the balance frame 52 forguiding the coin into thickness gauging engagement with the levers TB,15, of'the gauges'E, F, respectively, asbest seen inFigu-res'fi and 7,the'wrist-pin 43 meanwhile engaging theportion c ofthe cam 42 forforwardly returning the slide 0 to coin-weighing position, that is, for;registration of the notches 58' with the apertures 56. The balance D,thus grippingly supporting the coin in cooperation with thethickness-gauges E and F, is now freely oscillatorily suspended-on itsfulcrums 54 for gauging the weight of-the coin, the wristpin 43 duringthis operation engaging the dwellportion d of the cam 42, After'a briefinterval of time, sufficient to allow the balance D to come to rest incoin-weighing balanced position, the cam 33 actuates the lever 89 incircuit closing direction for engagement of the contact 88 with thecontact 86' if the coin ISI is of proper or predetermined weight, asindicated in Figure 10. Obviously, engagement of the contacts 86', 88,is prevented when a coin oi. greater or lesser weight than thecorrectweight is deposited. in the machine, the weight of "the impropercoin causing the frame 52 to balance-with the arm 86 angularly disposed,the contact being then swung to one side or the other of the contact 88and hence out of the path of movement thereof, as indicated in; Figure11, 'Atthe same time, the cam I31 closes the switch t38,'which remainsin such closed position during the actuation of the distributor Gandselectdr H, as presently appearing. i H

Assuming the deposit of a coin of proper weight in the balance D,electrical current flows from the switch I38 throughthe balance :switchcontacts 85, 88., thence'through arm 86 and lead 95, through conductingbolt 13 to thecontact spring 13. If the coin be of not less than minimumthickness, the gauge E causes electrical connection to be furtherestablished through the contacts 12,, E3, thence through pigtails 96 to,the contacts 18. And if the coin be of not more than maximum thickness,electrical connection remains established through one or the other ofthe pairs of contacts 13, 19, or-both of them, of the gauge F, and fromthenceto the magnet 28 oi the selector H for shifting thefollowerII8.-to the inside of the shifter-cam I121 and onto the accept-cam I23,as best seen in Figure 10.

However, if any of the foregoing conditions remains unsatisfied, that isto say, if the coin be of improper weightor dimensions, the abovedescribed electrical circuit will be interrupted or fail to beestablished at one or more of the several switching points depending onthe particular-defect in the coin. In such event, the magnet I28-remains de-energized and the follower I;I8'is engaged by thereject-shifter cam I21. which :acts to throw the follower onto thereject-cam I22, as best seen inFigure l1;-

Following the outlined operation, which terminates the'weight-gaugingperiod of the operative cycle of the machine, the wrist-spin 43 engagesthe portion a of the ring-cam 42 allowing. the levers 38 to be forwardlyactuated by resilient members Ma for returning the. slide C 'to normalor coin-receptive position, the plungers 23 and bar 25 moving withtheplate"I1,in"retracted position thereunder for uncovcringthechute Inc,the stops34' of the' side bars leer slide'C engaging the lugs st forforwardly shifting: the plate 59 for discharging the coin from the scaleD into the coinichute'ltii. 'iIn the meantime, as

the slide C approaches'its extreme forward position, the stops 23impinge the plate-28'for automatically shifting the plungers 23 from theblock 21 into norinal position: extended therefrom ,for deposit ofanother coinv inthe machine. For the remainderof the operativecycle, ofthe machine, the wrist-pin 43 engages the .dwell; f of :wthe cam 42. n 7Z i If thecoin'is selected asacceptablethe cam I23 then actuatesthefollower H8 in. upward dis rection for correspondingly tiltingthelvalve, I09 for rearwardly discharging the coininto thecoin-hopperofthe machine, the switch- I33 being likewise actuated forengaging the contacts I32, 133a. .At the same time,vthe cam ,I39 closesthe switch MB. Current hence flows irom the switch I38 through the leadI5I to arm I32,,and contact I33a, from which latter the current-flowdivides; part serving to illuminate the green signal I43 fortindicatingthe acceptance of the coin and part passing through the switch I40 forsuitable operation of the vending machine, as best seen in FigurelZ. Butif the coin'is rejected, the camHI2Z actuates-the follower} I I8;indownward ,dire'ction'for tilting the valve I09 fqrreturning the coin-tothe customer, that is,,for ejecting the coin from the machine intothereject-trayllld I v In such case, as willgbeunderstood, the contactsI32, I 32b, remain in normal engagedposition, theswitchHD and signal I43being hence V disconnected.- Current .then-flowsgfrom the switch 138throughthe contacts 132, I331), to the redsignal I46 only, as shown inFigure 13, for

.indicatingto the customer, by illumination of the signal, I46, therejection of thecoin. V The distributing operation having been com,-pleted, the-cam I31 acts to open the switch I38, following which thecycle is completed when the cam I35 acts to open the cut-off switchI36.;;

Figure =21 diagrammatically illustrates the the coin selecting anddistributing mechanism of the machine. Normally, as indicated by. the

dotted lines, the-distributor Q is actuable for functionalelectro-responsive relationships of by the maximum thickness gaugeF, themini-' mum thickness gauge E, and the weight-gauging balancer D arefully satisfied by the coin, that flow of current in; the electricalcircuit associated with saidgauginggmechanisms is established forenergizing the selector H, with consequent actuation of the distributorG, hence responsivelyto said current flow, for accepting the perfect oracceptable coin.

It will, however, be understood that the use of the machine is notconfined to gauging coins, my invention being .adapted for accuratelyand effectively gauging other objects capable of differentiation byreason of their size and weight, such other objects being commonly knownas checks, slugs, or the like. Also, by obvious modiflcations of theapparatus, checks and coins of other than circular outline may besuccessfully selected and sorted by the mechanisms described.

I may here point out that the thickness gauging operation isbothmechanically and functionally coincidental with the weighing operation,inasmuch as, during the-actuation of the selecting mechanism, the coinor check is firmly gripped or held in thickness gauging position adefinite distance from the fulcrums of the balance D, hence,

the coin, once deposited on the balance frame 52, is not disturbed ormoved until the thickness and weight of the coin have been measured andthe future course of the coin through the machine then and theredetermined.

Other novel features of my invention reside in the manner in which thedeposit of a metal check or coin acts to initiate the operation of themachine, thus obviating the use of manually-controlled buttons,plungers, or the like; the means for'feeding the coin in a positivemanner, not dependent upon gravity, to the gauging mechanism, andafterward, for in like manner removing the coin therefrom; the manner inwhich the distributing mechanism is actuated independ ently of and afterthe completion of the gauging operation, thus enabling the separationand use of the distributing means at points remote from the gaugingmechanism; the use of the camoperated switches, whereby the electricalcircuits are most economically normally de-energized, for establishmentof current flow, if any, during but a momentary period; the meansprovided for adjusting the gauging mechanism for effecting the precisionrequisite for accurately distinguishing good from spurious coins and thelike; and the novel mode of visibly indicating to the customertheacceptance or rejection of his coin.

The apparatus, as I have stated, is adapted to control a vendingmachine, telephone'pay station, toll gates, ticket sales machines, orother apparatus which may be built to operate by electric impulse, andit is to be understood that the coin selecting apparatus and theactuated mechanism or machine may be placed at some distance apart. 7 I

' It is further to be understood that the conformation of some coinsmight require more than two contacts 15, in order that one of them finda low place or valley in the coin. In other words, it might bedifficult, on a quarter or half dollar, for instance, to so space thetwo contacts shown that, if the coin was turned in a certain position,both contacts would be lifted, and the presence of a third'would benecessary to'determine the valley measurement; and that other changesand modifications in the form, construction, arrangement, andcombination of the several parts of the apparatus may be made andsubstituted for those herein shown and described without departing fromthe nature and principle of my invention. 7 v I Having thus described myinvention, what I claim and desire to secure by Letters Patent is- 1.Coin-selecting apparatus comprising, in
